Application March 20,

6 Claims.

This invention relates to unit assembly pressure control fittings, and more particularly to the construction of a fixture for the selective control of the discharge water to two outlets where the control element of such fixture is constructed as a removable unit.

Pressure control fittings of the type here under consideration are known in the art, particularly as disclosed in and by the Schossow Patent No. 1,256,600 of February 19, 1918, for Shampoo spray.

. In the'use of permanently installed fixtures such as sink fixtures, combination bath and shower fixtures and the like, the use of a structure like that disclosed in the Schossow patent is impractical because of the'fact that the fixture must be completely disassembled in order to permit a repair or' replacement of worn parts. In this type of installation wherein the fixture tures utilized be of such construction as to permit their ready disassembly for the purpose of repair or replacement. as occasion demands.

It is therefore an object of this invention to two water outlets and in which fitting there is included a unit pressure control valve assembly adapted tobe removed as a unit through one of said outlets for the purpose of repair or replacement. I 7

Another object of this invention is to provide a unit assembly pressure control fitting in which there is provided a carrier and which carrier is formed and constructed so as to include a pressure control valve all in unit assembly, which unit assembly and valve structure includes a the fixture and a pair of water outlets corre sponding tuthe water outlets of the fixture so mounted in the fixture as to permit removal thereof through one of the fixture outlets.

Other objects and advantages of this invention it is believed will be apparent from-the following detailed description of a preferred embodiment thereof as illustrated in the accompanying drawings. In the drawings: Figure l is a diagrammatic view of a shower and bathtub fixture inwhich our invention is incorporated;

Figure 2 is a front elevation of the piping and illustrated in Figure 1.

itself may be completely embedded in the wall structure of the particular building wherein the fitting is installed, it is necessary that all fixv 1937, Serial No. 132,124 (01. 277-4) Figure 3 is a sectional elevation of the structure embodying 'ourinvention illustrating the same as connected with fragments of the pipes as illustrated in Figure 1.

Figure 4 is a sectional elevation similar to Figure 3 illustrating the pressure controlled valve 'as moved to the closed position to discharge water through the opposite outlet of the fitting from that illustrated in Figure 3.

Figure 5 is a sectional end elevation taken substantially on the line 5-5 of Figure 3.

Figure 6 is a fragmental front elevation mainly invertical section of a modified form of structure embodying our invention illustrating the same as adapted to a sink fixture and spray combination.

Figure 7 is a sectional top plan view taken substantially on the line 'I-I of Figure 6.

In the modification of our invention illustrated in Figures 1 to 5, I indicates a hot water supply pipe and 2 a cold water supply pipe, the supply of water from which is collected through valvesv 3 and 4 as admitted to the inlet 5 of the casing 6 of the control fixture I. The casing 6 also includes two outlets 8 and 9. In the outlet I is connected the conduit III which leads upwardly to'the shower head H. In the outlet 0 is fitted the bathtub spout I 2. The casing ,6 is divided by the partition I! between the inlet 5 and the outlet I.

In order to control the direction of flow 'of the water admitted to the casing 8 through the inlet 5 to selectively discharge the water through either the spout I! or the shower head II, a pressure controlled valve means is provided which is formed as a unit assembly so that the entire valve unit may be removed from the casin 6 by merely removing the spout I2.

In this mannerrepairs required to be made in this fixture may be made simply and economically while the casing 0 remains in position and without necessity of disturbing the setting of any of the fixtures. This unit assembly includes a carrier I which is provided with an axial passage ii. The carrier I4 is likewise provided with a securing flange by means of which the carrier is threaded into position so that the stop flan e Il thereoi'engag'es the annular shoulder ll formed in the partition IS. The carrier II is provided with an inlet a: e or a plurality ofinlet ports H in registry with the inlet 5 ot the casing 0. The carrier I4 is likewise provided with outlets 20 and 21 corresponding to the two discharge outlets and 9 formed in the casing C. y

Mountedaxiallyoitheca;rrierllisapressure controlled valve assembly '22 which includes a valve head 23 which is adapted to seat on the inner end of the carrier l4 and close the passage 20. The stem 24 of the valve 22 extends axially in the axial passage Iiand is provided with an enlarged guide-head 25 by means of which the valve 22 is guided during its axial movement. The enlarged guide-head 26 likewise provides the valve head for closing the discharge outlet 2| when the valve is moved to the position illustrated ation to and from closed position.

The operation 01' the structure is: with the valves 3 and 4 open to the proper degree water of the desired temperature is admitted through the inlet 5 into the casing '6. The water passes through the inlet I! in the carrier i4 and is directed against the face 21 of the valve head 23in opposition to the force of the water being directed against the face 26 of the head 25. As the area of the face 21 is the larger, the valve 22 is moved to the position indicated in Figure 3, thereby closing the outlet 2| and opening the outlet so that the water is discharged up through 4 whereupon the water is discharged through the spout l2 into the bathtub. As soon as the valve 26 is open, the flow 01. water, however, will at all times reverse and discharge through the shower head II.

The valve 26 may be at any suitable location in the system or may be of any suitable kind or character.

In the modified form of our invention illustrated in Figures 6 and. '7, similar parts are indicated by similar numerals with the addition of an exponent "a" thereto. This modification of our invention is particularly directed to use in sink fixtures wherein the spout l2 discharges into the sink and the spray head H is of the type used for spraying dishes or the like and is connected to the outlet 6' by means of a flexible conduit or hose l6.

In this modification of our invention, the water, that is, the hot and cold water in the pipes l' and 2*, is mixed directly within the fixture itself rather than being mixed prior to the admission of the water to the fixture, so that the fixture casing 6 includes a pair of water inlets 5', 5.

As in the previous modification .of our invention, this sink fixture modification includes a carrier l4- in which the pressure actuated valve is mounted as a unit assembly sothat by removing the cap 36" .by means-o1 which the flexible conduit I6 is secured to the outlet 6*,

the unit assembly may be liited out i'or repair or renewal as occasion may require.' Thecarrier 14 has a pair or water inlets ll, I! in registry with the water inlets I, 6, and is provided with the pressure"conditions within the fitting, the

direction in which the water is discharged from .the v Water is admitted to the valve assembly in this modification through'the water inlets l9 and passes either directly through the outlet 9 to the spout l2 and likewise passes through the port or ports 3| formed in the valve head '23. The valve head 25'- will move to position to close the outlet 9'-.

In the operation of this structure, with the water admitted through the inlets I9? under pressure, normal action of the water is to unseat the valve head 23 to permit the water to be discharged through the spray head II.

as illustrated in Figure 6, the valve 22 will be moved into position to discharge the water through the outlet 9' and spout l2. As herein illustrated, the valve 26 is of the'spring-closing constructionwhich includes a casing 33 in which a valve is positioned. The valve is normally held in closed position by means of the spring 34 acting between the partition 35 and the shoulder washer 36 mounted upon the stem ofjthe valve 26. Spring 34' thus normally acts to seat the valve head 31, closing the passage of water to the spray II;

Having fully described our invention, it is to be understood that we do not wish to be limited to When, however, the valve 26 is in the closed-position the details herein set forth, but our invention is of the full scope of the appended claims.
